2. Nuclear War and Africa Nuclear war does not have to happen in a country to have catastrophic impact on that country Global climate disruption from a nuclear war anywhere on Earth would affect food supplies and food costs worldwide 1 billion casualties of “nuclear famine” Even without nuclear war, spending on nuclear weapons drains resources needed for health and development International Physicians for the Prevention of Nuclear War

3. Climate Consequences of Regional Nuclear War Scenario 100 Hiroshima-sized bombs detonated over cities in India and Pakistan International Physicians for the Prevention of Nuclear War

4. Climate Consequences of Regional Nuclear War 20 million fatalities Extensive radioactive fallout Global climate effects lasting a decade or more International Physicians for the Prevention of Nuclear War

5. Climate Consequences of Regional Nuclear War Nuclear explosions ignite fires that burn whole cities Soot lofted high into the atmosphere absorbs incoming sunlight Dramatic decrease in amount of light reaching the surface Large, rapid drops in surface temperature International Physicians for the Prevention of Nuclear War

10. Nuclear War: The Impact on Agriculture Sudden cooling, decreased sunlight, less rainfall shortens growing seasons; reduces crop yields Stratospheric ozone depletion damages crops sensitive to UV-B Disruption of petroleum supplies affects use of farm machinery and fertilizer and pesticide production Radioactive and toxic contamination takes farmland out of production Collapse of distribution system International Physicians for the Prevention of Nuclear War
